TOtZZZ whom it may concern Be it known that 1, MARTIN NVILLIAM BROWN, a citizen of the United States, residingat Galveston, in the county of Galves- 5 ton andState or" Texas, have invented certain new and useful Improvements in Devices for Treating Exhaust Gases; and I do hereby declare the following to be a run, clear, and exact description of the invention,

such as will enable others skilled in theart to which it appertains to make and use the same.

The present invention relates to improvements in devices for treating exhaust gases,

and has tor an objectto provide a device for use in connection with gasoline or other engines in which the exhaust gases are delivered directly on top of a body of water, causing the water to become agitated and heating the water so that vapor is termed. The vapor and agitated water extinguishes any sparks or fire that may be in the exhaust gases.

Another object of the invention consists in providing a device of this character in which the exhaust gases are bathed in such a way as to prevent the agitated water from being blown out of the device, andat the same time, trapping any sparks or fire that may be in the exhaust gases.

A further object of the invention lies in providing a casing foruse with an internal combustion engine in which a body of water will be prevented from rising or shifting in the casing.

A still further object of the invention lies in providing a casing into which the exhaustv gases are let out through a gauze strainer to act as an additional guard to ex- 40 tinguish sparks.

A still further object of the invention resides in providing an outlet chamber approximately in the center of the body of the easing, thereby insuring a" uniform level of water at the point of outlet, and preventing the water from being blown out when ascending ordescending hills or grades.

With the foregoing and other objects in view, the invention will be more fully described hereinafter, and will be inoreparticularly pointed out in the claims appended hereto.

In the drawings, wherein like symbols refer to like or corresponding parts throughout the several views;

haust pipev Figure 1 is a longitudinal section, with parts shown in elevation, of an improved device constructed according to the present invention.

Figure 2' is a longitudinal sectiontakentg on the hue 22 of Figure 1.

Figure 3 1s a perspectlve view ot'the ex- Figure 4: is across section taken on the line 4:l in Figure 1, and V Figure 5 1s a perspectlve view of one of the water check plates.

Referring more particularly to the drawings, 6 designates a substantially cylindrical casing of the device which may he made .pipe. The opposite end of theexhaust pipe 30 7 is closed, and the pipe is slotted'longitudinally as indicated at 9, the slot being directed downwards so asto direct the exhaust gases at substantially right angles against the surface of a body of water or other liquid held in the casing 6. The water is let in through a filling neck 10, kept normally closed. by the plug 11. The water may be poured to any suitable level, and the water is prevented from running from one end of the tank to so the other by the motion of the vehicle be cause of the presence of the water check plates 12, which are substantially semicircular and provided with the attaching flanges 13, by which the plates are riveted or otherwise secured within the lower portion of the casing 6. The plates are provided with a suitable number of perforations 14. in order to permit passage of the liquid from one side ofthe plates to the other, the plates forming compartments in the lower portion of the casing, and it is not intended to have the liquid body in separate coinpartments, but the body of liquid acts pretterably as a whole, the plates, shown to be 1 four in number, being merely located at spaced intervals within the liquid body to avoid the undue motion thereof incident to travel of the vehicle.

Baffle plates 15 and 16 are secured in the casing 6 at the upper portion thereof and at opposite sides of the exhaust pipe 7, the pipes 15 and 16 being arranged diagonally and in downwardly convergent relation. The lower ends of these ba'tlle plates are spaced from the partitions or check plates 12, and the lower ends of the battle plates do not intersect the line of the slot 9 in the exhaust pipe. In other words, they do not interfere with the direct impingement of the exhaust products against the surface of the water body, but they act to prevent the water and exhaust gases from being blown out above the casing and they act to trap any sparks and fire that may he in the exhaust gases.

At the center of the casing. above, and communicating with the same, is a chamber 17, just above the central part of the exhaust pipe. this chamber having the outlet pipe 18 for the exhaust gases after the same have been properly expanded and cooled in the mutller. A gauze strainer 19 is shown as depending from the chamber 17 and the outlet pipe 18. this strainer being cylindrical in form and closed at its bottom. and is of substantially less diameter than the diameter of the chamber so as to permit the enveloping by the cooled exhaust gases. The strainer will act as an additional guard to prevent the passing o f sparks in case the water should become -ex hausted.

In the use of the device. the exhaust products enter through the pipe 7. issue downwardly through the slot 9, and impinge against the surface of the water between the two baffle plates 15 and 16. The water is agitated to a considerable extent, apor is formed. and the water and vapor effectually extinguish all sparks and cool the The tendency will be for the water to be driven up to the opposite outer face of the baffle plates 15 and 16, and the water being splashed up in these pockets, will be prevented from overflowing, and the only water that escapes will be that which is vaporized and passes out through the outlet pipe 18 with the other exhaust products. The outlet chamber 17. being placed centrally of the casing 6, there will always be a umform level of water at the central point. and this will always prevent the water from being blown out. particularly when the water is at an inclination in the casing due to the position of the vehicle on a grade.

It is obvious that various changes and modifications may be made in the details of construction and design of the above specifically described embodiment of this invention without departing from the spirit thereof, such changes and modifications being restricted only by the scope of the following claims.

What is claimed is:

1. A device of the character described comprising a casing adapted to hold a body of liquid, an exhaust pipe having an opening to direct the exhaust products downwardly against the surface of the body of liquid, baflie plates at the sides of the exhaust pipe and forming pockets to catch the agitated water and gases, and an outlet for the gases after passing in contact with the liquid.

2. A device of the character described comprising a casing adapted to contain a body of liquid, a slotted exhaust pipe in the upper portion of. the casing adapted to direct the exhaust products against the sur face of the body of liquid. inclined halite plates at opposite sides of said exhaust pipe. and an outlet chamber communicating with the central upper portion of said casing.

3. A device of the character described comprising a casing adapted to contain a body of liquid. a slotted exhaust pipe in the upper portion of said casing, inclined baffles at opposite sides of said exhaust pipe. an outlet chamber communicating with the upper central portion of said casing, and a strainer in said outlet-chamber.

t. A device of the character described comprising a closed casing adapted to contain a body of liquid. means therein for avoiding the undue motion of liquid therein. baiile plates at opposite sides of said exhaust pipe. and an outlet chamber communicating with the upper intermediate portion of said casing.

5. A device of the character described comprising a closed casing, means for introducing a body of liquid thereto, spaced. transversely extending perforated check plates mounted in the lower portion of said casing, an exhaust pipe extending into the upper portion of said casing for directing the exhaust against the surface of the liquid body, and an outlet at substantially the cen tral portion of said casing.

6. A device of the character described con'iprising a closed casing. means for in troducing a body of liquid to the casing. perforated check plates mounted transversely at intervals in said casing, a slotted exhaust pipe for directing the exhaust products downwardly against the surface of the liquid, an outlet chamber comniunicaiin; with the central upper portion of said casing and a gauze strainer of small diameter in said chamber adapted tobe enveloped by the products therein.
